A mad-- samedi in 3j passes mmmd n hmmm cent to a platform 56 mounted onlment, it will be clear that guidewa ,s formed in the ends of thecarriage frame 22. Suitable adjusting screws bear against the boxes 3ft,for the purpose of tightening the conveyer, will be readily understood.In order that the material will not pass over the edges of the conveyerbelt, guide strips 36 are prefer-'ably secured upon the upper edges ofthe side frames 22, and overlap the margins of the conveyer. belt 29, asshown in Fig. 11. lith this construction, it will be evident thatinaterial deposited on the conveyor by the 'shovel elements 26, will bemoved longitudia rack 42 with which meshes a pinion lf3y carried by thelower end ot a vertical shaft 44.- journaled in the carriage base. Itwill be evident that by operating the pinion 48,

the carriage will thus be caused to have a movement transversely orlaterally of the truck member. F or the purpose of securing thismovement, the following `mechanism is preferably employed. The upper endof the shaft 44 has secured thereto a pinion 45 that is in mesh withoppositely disposed bevel gears 46 loosely journaled on a horizontaltransversely disposed shaft 47. Either of these gears 46 can he clutchedto the shaft by suitable clutch elements 4SI suitably feathered on saidshaft and operated by cam elements 49 located alongside the same andconnectedby links 50. The link 50 has a connection with a crank 5lcarriedby a rock shaft 52, and this rock shaft has a gear connection 53with an actuating-shaft projecting beyond the casing or carriage base87, and provided with a handle lever 55. The lever, as shown esfpeciallyin Figs. l and 4 is disposed .adjaone side of the carriage, and on whichthe operator of the machine stands. With this arrangeeither gear wheel46 can be driven, and ion can be rotated in either of oppositedirections, so that the carriage can be moved back or forth. These gearscan also both be unclutched .from the shaft 47, in which case the pinionis stationary. The shaft 47 is provided at one end with a sprocket wheel57 around which passes a sprocket chain 58 that also passes around asprocket the shaft 47.

wheel 59 on a shaft 6G that is parallel to The shaft 6() carriesla wormwheel 61 which ,is in mesh with a worm 62 fixed to a counter-shaft 63journaled consequently the pin! above the worm wheel 6l at right anglesto the shafts 47 and 60. The shaft 63 has a coupling 6l adapted to beengaged with the shaft of `a motor, indicated'at 65, which vmotor islocated within the casing 37 or base of the carriage. vWhile an electricmotor is preferably employed, it will be understood that any suitabledriving power may be utilized.

The motor shaft 68 carries a second worm 66 which is in mesh-Vith a gearwheel 67 loosely journaled on a shaft 68. This gear wheel 67 can beclutched to the shaft 68 by a member 69 feathered on said shaft. The

vmember 69 is`operated by a crank whl 70 carried by a rock shaft 71having a crank arm' 72, and this crank arm 72 has a link connection 73,as shown in Fig. 7, with a crank on a second rock shaft 74 that projectsfrom one side 'of the carriage base or casing, and has a pedal 75 foroperating it. The shaft (i8 is provided at its ends with sprocket w eels76, around which pass s cket chains, indicated at 77 in Fi 3, t esesprocket chains operating one ofgthe drums 31, and consequently theconveyor.. The terminal drinn .32 has ysprocket wheels. 78, around which.pass sprocket chains 79 operating on sprocket wheels 80, fixed to thedigging drum 25. With this arrange ment, therefore,- by clutching theear 67 to the shaft 68, it will be evident tiat the digging andconveying mechanism is operated from the motor As above explained, therack and pinion effects a transverse movement of the carriage on thetruck-member, and mechanism is provided for causing the said carriage tohave a swinging movement on an axis at the rear or delivery andconsequently beyond the truck member. This is indicated in dotted linesinr Fig. l. and is accomplished as follows: A link bar 81 is providedhaving a pivotal connection 82 at its front end liavinga pivotalconnection 83 at its rear 'end with the' bottoni of the carriage base.

This link is so proportioned that it will swing, as indicated in Fig.'1, to one side or the other accordingly as'thc digging cnd 115 unglaterally, and conofthe carrlage is sw sequently the pivotaxis., insteadof being directly upon or intersecting one end of the truck, is placedbeyond said-truck, and at the delivery `end of evident, therefore, thatthe delivery end ol the carriage maintains a central position withrespect to the track, upon which the truck islocated, and consequentlywith respect to the cars placed beneath the same.

This central position is maintained entirely irrespective of thedistance the receiving or diggingr end is offset from the truck. Thereis, however, a tendency of the entire carriage to move bodily in atransverse dend of said carriage, 10.5
